  1. Not sure I will do ITB’s. I have a custom plenum I’m building for NA or turbo. One TB to mess with and tune . I do like the look and maybe I’ll go that route some day . I have a diesel manifold that I would love to run also - just something different .
  2. Just love breaking this engine in! The torque is very strong. I’ve limited myself to 5500 at this point, but still pulling very strong. Have to be careful not to hit it too hard in lower gears or I just break the tires loose. Able to run 35 degrees timing so far, but probably close to the limit. Need to break this bad boy in and and get to the dyno to dial it in. Running very similar tune I did with my 2.4, just more fuel. Seems to be doing rather well on the MPG- beauty of EFI. On the dyno I will probably advance the cam a bit too if I can get away with it. I’ll see where the power curve comes in. Took a peek at the cam and everything looks peachy. Just finishing up the install of my old motor in to the customers car. After it’s gone I can devote more time to tuning. Right now just driving around and letting Megasquirt do it’s thing.
  3. My 2 cents . I agree with the diagram above. Your chain wears which changes the relative position of the cam to the crank. Flipping around the sprocket to a different index hole and ALIGNING the cam to that hole advances the cam. I’ve done a lot of cam degree-ing with a fresh chain and sprocket . You have to move the cam in order to get the sprocket to index in. Nothing gets moved on the chain. Not sure if that helped or not.
  4. Lovely ! The cam makes for a very exotic sputter at idle. Trying to be patient before thumping on it too hard. Hasn’t seen more than 4500 rpm yet. Much more torque than the 2.4 for sure .
  5. I offered to paint the engine for the guy so he wouldn’t have a red engine in a green car. He picked gold - and I’m digging it- lol - get it!
  6. I just tried it and it worked fine .
  7. Really gets fuzzy when you decide you want to advance the cam 9 degrees
  8. Not sure anyone referencing this thread will get anything out of it but confusion.
  9. How much Cylinder pressure ? Lots! 97B3B5AA-2FDF-4291-8C4F-C375C5E536AC.MOV
  10. Rut roh - maybe more than I thought ? And I shaved .005 off the block -eek Should be .049 or 1.25mm thick.
  11. Well the MN47/54 ran today for the first time . Talk about nervous . 11.25:1 sounds pretty good out the tail pipe. This cam sounds pretty radical too. Only ran it long enough to move my car out of the way, but wow- can’t wait !
  12. I would say true. Closing the intake valve earlier will get some low end grunt .
  13. No - I believe it’s 4 . I was running an adjustable anyway .
  14. I was running 8 degrees in advance and wouldn’t have minded some more . Running the ISKY 290 duration put the power band up pretty high. About 4K+ is where she started to really “ come on the cam “!
  15. Don’t worry about chain slack, go for the CR you want . Move the guide to take up slack. Advance cam timing a bunch and roll with it! I have .050+ off my e88 , no shims . Plug in 39cc chamber numbers for the MN47! I got my fingers crossed for my engine .
  16. I see you found the thread . I just cut and notched my shaft carefully with a cut off wheel. Curious what year sensor you bought and what you got for the connector. Believe it or not I never finished what I started . One main reason is I was having difficulty finding the correct wiring harness connector . I ordered one and it wasn’t quite shaped the same way. Got sidetracked and never finished the install. Car ran well with batch fire for now. Definitely takes up less room!
  17. You need to look and mark your timing marks on the pulley carefully. I almost bet you are sitting at 20 BTDC at idle and not 25. More than likely you have 17 degrees of mechanical advance with that dizzy and that would total you out at 37 WOT. 20 degrees idle advance would start and idle easier without choke because all that advance makes for a strong idle. Does your vacuum advance work? That’s where you might run into issues . You might be adding too much advance at cruise and be causing detonation that you can’t hear . Might suggest getting an Advance type timing light to check full mechanical advance and vacuum advance. Check your vacuum advance is working properly and not sticking I’ve run all my motors with close to 20 degrees at idle , with no vacuum advance. I also had cams that ran better that way. Figure out what dizzy you have with the chart below. Just 45 miles south of you I noticed!
  18. With a red engine? That’s what he will have -lol. Of course it has a blue engine in a green car now
  19. Sold my engine today ! Time to move on to my L28 build. Buyer brought his Z to me to install his newly acquired motor. He was fortunate enough to actually drive his motor before he bought it. He was smiling too much to barter a better deal. So now I have a double engine swap to do.
  20. Have you seen the thread on Hybridz using the Jeep cam angle sensor ?
  21. If you are trying to find a coolant leak in the timing cover you need to pressurize the system. Go to Oriellys or Autozone and rent a coolant pressure tester . Put 15lbs on there or so and take the valve cover and listen. It will hiss if it’s pissing coolant . You might even be able to see it will a flashlight looking down the chain .
  22. Impressive for sure . I bet that ride is a rocket!
